Wi-fi and obesity fears in papers

Health scares of various kinds make several front pages.

The Daily Mail says Britain is facing a "cancer time bomb" because of rising levels of obesity.

It quotes Dr Greg Martin, who says excess fat around the stomach stimulates production of the hormone oestrogen which can increase the chances of developing a tumour.

The Independent says Dr Martin is frustrated that so few people are making the "simple changes to their lifestyles" that could significantly lower their risk.

Radiation fears

Other papers cover calls made by the chairman of the Health Protection Agency to investigate the possible risks of wireless internet in schools.

The Daily Telegraph says Sir William Stewart is reflecting growing fears about the effects of radiation on children.

The BBC's Panorama programme found emissions were three times higher in a school than from a mobile phone mast, the paper reports.

But the Guardian called the BBC's investigation "grossly unscientific".

Minute's silence

The anguish of the family of Madeleine McCann also remains in the news, as her father returns to the UK for the first time since she disappeared.

The Times reports that the McCanns are considering hiring private detectives to help find the four-year-old.

The Daily Mirror, meanwhile, says a minute's silence will be held at noon on Monday in Portugal to remember Madeleine.

Kate and Gerry McCann plan to set off on "a worldwide mission" to the "four corners of the earth" to find their daughter, the Daily Express claims.

Feeling fines

The Sun is one of several papers reporting the introduction of new digital speed cameras.

"Gatcha", the paper exclaims, saying the updated Gatso model "is expected to double the number of speeding tickets issued" and raise £120m in fines.

Elsewhere, Victoria Wood is praised for her double triumph at the BAFTAs.

The Daily Mail says "her serious side is just as well developed as her funny bone", after the 54-year-old was named best actress for her performance in the ITV drama Housewife, 49.
